About Me

I am a senior undergraduate in Computer Science at the University of Science and Technology of China (USTC), School of the Gifted Young, advised by Prof. Xue Chen.

My research interests broadly lie in theoretical computer science, especially in coding theory and graph algorithms. I also participate in competitive programming, winning a Bronze Medal (9th place) at the ICPC 2025 World Finals in Baku.

Previously, I was a research intern advised by Prof. Zeyu Guo (Ohio State University, Summer 2024), Prof. Xin Li (Johns Hopkins University, Autumn 2025), and Prof. Thatchaphol Saranurak (University of Michigan, remote).
